40th Birthday Gift. 1981 was a low mintage year for the 50p, making these cufflinks very rare. The Irish 50p Cufflinks were made as there were no other coins made that year. It means that they cufflinks, make a very unique set of cufflinks The 50p was a seven sided coin and featured the woodcock design. The coins are encased into the cufflinks and would be suitable for someone who wants something just a little bit different.
